Compound waterproof roll for construction of roof waterproof layer

Abstract

The invention belongs to the technical field of waterproof materials and in particular relates to a compound waterproof roll for construction of a roof waterproof layer. A middle layer of the compoundwaterproof roll is a fabric structure layer; waterproof functional layers are arranged on double faces of the fabric structure layer; modified asphalt reinforcing layers are arranged on upper and lower surfaces of the waterproof functional layers; sticky enhancement layers are further arranged between the waterproof functional layers and the fabric structure layer. Each waterproof functional layer is prepared from the following components in parts by mass: chlorinated polyethylene resin, polyurethane resin, chloroprene rubber, titanium white, hydrophobic silicon dioxide, an antioxidant and acoupling agent; the antioxidant is an antioxidant 1010 or an antioxidant 168; the coupling agent is a silane coupling agent or a titanate coupling agent; the material of the fabric structure layer isa polypropylene fiber on-woven fabrics or a polyester gridding cloth. The compound waterproof roll provided by the invention has excellent waterproof and water-resisting performance and has good mechanical characteristics and anti-oxidization performance; the service life is relatively long.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a composite waterproof coiled material for roof waterproof layer construction. Background technique [0002] Waterproof membrane refers to a waterproof material product made by impregnating asphalt or polymer waterproof material on the carcass. It is provided in the form of a membrane and is called waterproof membrane. Waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage. As the non-leakage connection between the engineering foundation and the building, it is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. The main products are asphalt waterproof membrane and polymer waterproof membrane. [0003] Bituminous waterproofing membrane has excellent water resistance, strong bearing capacity, can remain unb...

AI Technical Summary

Problems solved by technology

Large, but the heat resistance and flexibility of the asphalt waterproofing membrane are relatively poor, and the material may drip and bubble at high temperature, which will affect the waterproofing performance of the membrane even more, and it is easy to break when subjected to curling and shearing forces

[0004] The polymer waterproof membrane has good waterproof effect, excellent flexibility and tensile strength, but the material has poor oxidation resistance, is easy to age, has a short service life, and has high production costs.
